If you can swing $99 then this might be something to check out. I use one very sucessfully with the asterisk open source PBX and it does quite well. To do what you want to do the configuration is quite trivial also. You would have to supply the audio source in either mp3 or gsm audio and could even create a simple menu that would allow them to select a story to hear.
